Android http download at very very low priority

My Android app needs to do a large (~150MB) download in the background. I am using an intent service and doing this in the background.

The problem is that this big download cloggs all other downloads.

(I'm using Volley+Glide for image downloads in the app and OkHTTP for the large file download. I would use Volley for everything, but since it's not recommended for large files, I'm using okHttp.)

Volley has a way of setting download priorities, but AFAIK, that's only used to determine WHEN a download starts, not for the % of bandwidth a d/l uses.

I was not able to find a way to set okHTTP to download at a very low priority.

Ideally, what I would like to do is just set the large okHttp download to a very low priority, and it would let everything else download.

Create a class called ThrottledSource that extends Okio’s ForwardingSource. This class needs to limit the kilobytes per second. You can see examples of throttling a stream in MockWebServer.java.

When you're done you'll have a stream that downloads slower than it needs to. That'll free up bandwidth for other transfers.

  1. Split the file into smaller chunks, eg. split zips
  2. Download the files with the IntentService when the app is not running (use JobScheduler)
